The Article feedback project is an initiative of the Wikimedia Foundation to engage Wikimedia readers in the assessment of article quality, one of the five priorities defined in the strategic plan. It is based on the WMF-developed ArticleFeedback MediaWiki extension called Article Feedback Tool (AFT) and deployed as of v.4 on all articles on the English Wikipedia. A new version (v.5) of the Article Feedback Tool is under development, with a new emphasis on engaging readers to participate more on Wikipedia.

Research reports from the first phase of AFT's deployment (up to v.4) can be found on this page.

AFT v.5 was initially enabled on a small sample (0.3%) of randomly selected articles from the English Wikipedia on top of a small list of high-profile articles. Visitors are randomly assigned to one of three buckets for testing purposes. Key metrics and a work plan for testing AFT v.5 are available on this page. Clicktracking data specifications are described here.

The first reports from phase 1 of the AFT5 experimentation are available. They report results on the difference in volume and quality of feedback as a function of the design and placement of the AFT widget. For real-time data from the current AFT5 tests, check the metrics dashboard and feedback stream, as well as data dumps.
